Types of Foundations
A mattress foundation is a low-profile metal frame or base designed to offer extra support for your twin mattress. It's not to be confused with a bed frame, which often comes with built-in foundations.
Most bed frames come with built-in mattress foundations, but if your foundation isn't sturdy, you'll need to buy a separate one. A weak bed foundation will have bed slats that are more than 3 inches apart or wouldn't have any support in the center.
There are different types of foundations for different types of mattresses. For innerspring mattresses, you should use a box spring as a foundation, while for memory foam, latex, or hybrid mattresses, you'll need a different foundation.
